| 1 | Sister Mary Joseph's nodule as the first sign of pregnancy-associated gastric cancer:A case report显示文摘Sister Mary Joseph's nodule is an inconspicuous and uncommon clinical sign of advanced malignant disease, especially gastric cancer. Pregnancy-associated gastric cancer is an extremely rare condition and can be difficult to diagnose, due to the absence or misinterpretation of symptoms as pregnancy-related. Diagnostic aids, such as a basic chemistry panel and imaging techniques, may not show any abnormalities. We present a case of a 37-year-old pregnant patient whose umbilical nodule was the first presenting physical sign of gastric cancer, which had metastasized throughout the abdominal and pelvic regions. | Sara Fill Andrei Taran Hans-Ulrich Schulz Stefan Kahl Thomas Kalinski Bobbie Smith Serban-Dan Costa | 2008 | World Journal of Gastroenterology2008，14，6： | 3 |
